Can any one simplify the YiHi joules temp control

[tehdarkaura]

Calculating the joules sounds interesting -- but saying how yihi is using this value is really all guessing until we get one in hand with joules and TP to see what it does.

Maybe it will be great, maybe not...

If they watched the joules to calculate average power dumped per time or hit and used that to keep it from going crazy on a nickle build (like my dna40 does randomly) that would be great...

If they are just introducing some new variables without any real gain (maybe to avoid some patent infringement) that's not so great.

in the end -- once we have them in hand the discussion becomes much more meaningful than stabs in the dark with no real insight.

Seems pretty simple to me to just contact Yihi and ask them to explain to you how they are controlling temperature (if they are)..... Evolv certainly explained it in many video's and etc... Why not just go to the source if ya really want to know... IMO....

Personally I would rather have a PB review -- his review sure shed plenty of light on the "claims" made by evolv.
Evolv sure is happy to hand back a cookie cutter reply to inquiries, but as PB pointed out ... they are not always very accurate in their claims.

I remember reading posts on here that supposedly came from evolv citing encrypted hardware in their DNA40's... also that a gold plating solves screen initialization issues... not exactly what i would call a very trust worthy source...

Yes Busardo's review was a real eye opener for me!

I actually thought he had a clue until I watched the DNA40 review.

Seems pretty clear to me that Yihi's interface lets you set the temp you want, and wattage, just like Devolvs board. But they're also letting you adjust joules, which could possibly give you more granularity, and allow for fine tuning. But I'm willing to bet there's a default mode that's just "Temp and Watts, leave me the hell alone and let me vape like I learned how to do last year with the competitors board"

lol -- some times the truth hurts when your supporting a product blindly my friend

Even some of the hardest evolv fanboys I have seen on here have ordered the VF3 Clone and said it works much better than the original...

TP isn't magic guys...

 

[Woofer]

That would Take some Technology that I have Not Seen in a e-Cigarette Atomizer.

Perhaps a Miniature Thermal Coupler? Or maybe via Infrared Waves?

Either way would be Expensive. And perhaps, Size Prohibited.

From the same source;

Thermocouples are voltage devices that indicate temperature by measuring a change in voltage. As temperature goes up, the output voltage of the thermocouple rises - not necessarily linearly.

And in my prior post we looked at resistive temperature sensing which is more linear and the method Evolv used to sense the coil temperature.
Are you Seeing a Pattern here?

What does that have to do with asking Yihi about their temperature control.... Reviewers only review and Yihi makes the board...Yihi should be the expert on their board... more so than a reviewer...imo...PB stated in print at the beginning of each video that it is only HIS opinion...and he is no expert in any of the technology he reviews imo...

So Busardo's opinions are the truth now!
I have two rDNA 40s one from pre order and one from cyber Monday.
They both work perfectly and are all I use now.
My opinion is different to Busardo's.

The only other device I own that he reviewed is the iStick20, he gave it a thumbs up.
My iStick is evil and unusable.

With mods I own, Busardo is twice wrong.

I trust a technical review over a marketing response...

bust out your O-Scope FLIR and dummy loads and show us how he is wrong then

I dunno?

I think I would have to Use a Mod that had this Chip in it to know what is Up with the Joules Display.

Or hear from more people who have one and Hear their Thoughts.

I been searching around the net plus sat through phil's review of the sx350 (not the sx350j) to see if he might mention anything about joules; nothing.

His opinions seem less steeped in bias then what you are putting forth imo.

Pretty sure i recall him giving that istick20 a thumbs down too. But hey, whatever facts support your agenda i guess.

According to what I saw on the site there appears to be a Joule "mode"

If that means that you can set the joules, its almost like setting/adjusting a 10 second cutoff effect.

Like I said, I don't know of Any e-Cigarette Device that Measures Heat Directly at the Coil.

I think an Affordable, Miniature System of Direct Measurement of a Coils Temperature would be the Single Greatest Milestone in the History of e-Cigarettes.

Maybe in the future... if so none of your favorite atty's would work....

If the Coil Temperature could be Measured Directly, then it Wouldn't Matter what you of Resistance Wire Alloy a person would like to use. And the Worries of Thermal Breakdown of things like VG or Sweeteners could be Controlled. It would Also account for Thermal Exchange of Wicking and Air Flow.

A Truly Revolutionary way to Vape. Set the Temp Limit and away you go.

I hope we get there One Day. And I'm sure we will. But I think the Coming FDA Regulations will Stifle the Evolution of e-Cigarette Technologies in Many Ways.

I hope we get there too.....vaping has come a long way thus far.....FDA regs....???? to be determined....

The thing is we don't measure heat directly.
We measure heat by noting material behaviour in its presence.
A T coupler monitors voltage change, a resistive temperature sensor looks for resistance change. (What Evolv is now doing)
A bi metal strip or analog thermometer rely on movement.
I am told IR is not a good method for coil temps.

What could this direct temp measurement be and how would one do it.
Using the coil as both the heat source and temperature sensor is brilliant engineering and it is as direct as can be.

BTW - What is the Benefits of "Soft" vs. "Power" Modes?
